A steam generator comprising a combustion chamber having funnel-shaped side walls in the bottom area thereof and an encircling wall formed from a plurality of steam generator pipes through which a flow medium can flow, wherein there area as little temperature differences as possible in the flow medium at the output of the steam generator pies. The steam generator pipes are, more particularly, arranged in the lower section forming the funnel-shaped side walls such that they are exposed to heat in as homongenous a manner as possible. According to the invention, the diameter of a number of steam generator pipes in the region of the funnel shaped side walls is different from that in the region of the encircling wall.
